IEC 60870-5-103

The point map for the 103 is different from the one shared by the IEC104 and DNP
protocols. IEC 60870-5-103 serial communications protocol is supported on the rear RS485
port only.
The DNP, 103 and Modbus can not be enabled simultaneously. Only one instance of
DNP3.0, IEC 103 or Modbus can run on the RS485 serial port.

All binary inputs are configured from FlexLogic operands. For a complete list, see Format
Code FC142.
The user must pay attention when configuring the function type and information number
of the different points, because they must be unique. There is no mechanism in the
EnerVista 8 Series Setup software or the front panel HMI to detect duplication of the
information index.
The IEC 60870-5-103 point lists always begin with point 0 and end at the first "Off" value.
Since IEC 60870-5-103 point lists must be in one continuous block, any points assigned
after the first "Off" point are ignored.
The cause of transmission is an unsigned integer which takes one of the values specified in
the following tables.
